[libvirt] [PATCH] RFC: maint: Sort public symbols within a release
by Eric Blake 24 Jun '19

24 Jun '19

In libvirt_private.syms, we have a policy of keeping blocks of symbols sorted by name - in fact, we enforce it during 'make check' with our check-symsorting rule calling out to a perl script. But libvirt_public.syms has been more cavalier over the years. 21 releases have been trivially sorted due to adding only one symbol; while the following 27 releases listed multiple symbols in alphabetical order, even if the symbols were not chronologically added in that order [1]: 0.0.3 0.9.5 1.1.0 0.3.0 0.9.7 1.1.1 0.3.3 0.9.8 1.2.5 0.4.2 0.9.9 1.2.8 0.6.3 0.9.10 1.2.11 0.7.5 0.9.13 1.2.15 0.9.0 1.0.1 1.3.3 0.9.2 1.0.2 3.1.0 0.9.3 1.0.3 3.4.0 [1] Case study: git log -p v0.9.9..v0.9.10 src/libvirt_public.syms shows 9 commits adding 9 APIs among 7 authors: 0b7ddf9e - trivially in order adb99a05 - appending happened to also be sorted order 1f7aa0ac - irrelevant (removing TABs, not adding symbol) 6714fd04 - added in sorted order 8f8b0802 - appended, out of order e1eea747 - re-sorted previous addition, and added in sorted order 02af3e13 - added in sorted order c471e55e - added in sorted order 99fd69c3 - added in sorted order The following patch changes the remaining 37 releases to do likewise, and documents the practice. Signed-off-by: Eric Blake <eblake(a)redhat.com> --- I'm not sure if we want this patch - it got much bigger than I was expecting. 37 releases is less than half of the total versions in the file, but larger than the number of releases that were sorted (where it is not even obvious if that was always intentional or by luck). We could also decide to adopt a policy of listing symbols in the same order as remote_protocol.x (although not all symbols go over RPC), but that seems like it would be even more churn and harder to enforce. Ideally, if we DO want this patch, we should also teach 'make check' via src/check-symsorting.pl how to enforce it on the public file; as I did not do that, this is marked RFC. The diffstat shows a delta because I deleted 5 blank lines and added 2 comment lines. --- src/libvirt_public.syms | 313 ++++++++++++++++++++-------------------- 1 file changed, 155 insertions(+), 158 deletions(-) diff --git a/src/libvirt_public.syms b/src/libvirt_public.syms index 75f7fdfb0c..f9e0072352 100644 --- a/src/libvirt_public.syms +++ b/src/libvirt_public.syms @@ -10,6 +10,8 @@ # soname version info can't enforce this since we never # change the soname # +# Keep this file sorted by version, then by symbols within each version. +# LIBVIRT_0.0.3 { global: virConnectClose;

[libvirt] [PATCH 0/2] A couple coverity patches
by John Ferlan 22 Jun '19

22 Jun '19

Coverity has been tripped up a few more times recently... The memory leak patch probably I what I noted from Jiri's recent CPU series. The return value check is older. It wasn't clear though if the intention of the module was to ignore errors so I just chose to error out like other similar callers. If there's a better way - then other patches can be posted.

[libvirt] [PATCH v8.5 00/13] Checkpoint APIs (incremental backup saga)
by Eric Blake 21 Jun '19

21 Jun '19

This is a subset of v8 of incremental backup, focusing more on just the checkpoint manipulation code (as this had fewer review comments that still needed addressing). I think there is enough here that even if this lands in 5.5 while the backup APIs slide into 5.6 that we'd still have a reasonably usable set of APIs. I probably still need to double-check that creating checkpoints while an external snapshot exists gives a sane error, and that creating an external snapshot while checkoints exist give a sane error (in both cases, with plans to relax that error later once we finish our design); that can be done as a patch on top of these or if I have to respin this part of the series once more before 5.5. I do plan on tagging a v9 label of the full backup series, but that will be in a separate thread built on top of this one (hence naming this one v8.5). Since v8: - Completely drop the virDomainHasCurrentCheckpoint API (you get the same effect by calling virDomainCheckpointCurrent) - Defer the virDomainCheckpointHasMetadata API for a later day (if we ever want it); for now, all checkpoints require libvirt metadta - Expand the code to implement Checkpoint APIs for the test driver - rebase to master - Defer the Backup API work to a later series - Split out the handling of VIR_DOMAIN_CHECKPOINT_XML_SIZE into its own patch (that one is probably the most likely to need a respin, or even deferring it post-5.5 as adding flag support is different than adding new API) 001/13:[----] [--] 'backup: Document new XML for checkpoints' 002/13:[0121] [FC] 'backup: Introduce virDomainCheckpoint APIs' 003/13:[0004] [FC] 'backup: Document nuances between

[libvirt] [PATCH] Don't parse/format vram attribute for cirrus video
by Jonathon Jongsma 21 Jun '19

21 Jun '19

Since the cirrus vga memory size isn't configurable, we can ignore any 'vram' attribute when parsing a domain definition. However, when no value is specified, it ends up getting set to a default value of 16MB. This 16MB value is not used anywhere (for example, it is not passed as an argument to qemu), but is displayed in the XML definition. So by changing this default value to 0, it will also be omitted from the XML definition of the domain. Fixes: rhbz#1447831 Signed-off-by: Jonathon Jongsma <jjongsma(a)redhat.com> --- This is an attempt to apply the fix suggested by Gerd at https://bugzilla.redhat.com/show_bug.cgi?id=1447831#c2. I'm not totally confident that this is the right approach, since I'm relatively new to the code. Another approach might be to simply close the bug as NOTABUG since it doesn't seem that having this unused attribute in the domain definition has any significant drawbacks. src/conf/domain_conf.c | 2 +- src/qemu/qemu_domain.c | 3 +++ 2 files changed, 4 insertions(+), 1 deletion(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index c69d382d70..d06e094b11 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -15154,7 +15154,6 @@ virDomainVideoDefaultRAM(const virDomainDef *def, { switch (type) { case VIR_DOMAIN_VIDEO_TYPE_VGA: - case VIR_DOMAIN_VIDEO_TYPE_CIRRUS: case VIR_DOMAIN_VIDEO_TYPE_VMVGA: if (def->virtType == VIR_DOMAIN_VIRT_VBOX) return 8 * 1024; @@ -15172,6 +15171,7 @@ virDomainVideoDefaultRAM(const virDomainDef *def, /* QEMU use 64M as the minimal video memory for qxl device */ return 64 * 1024; + case VIR_DOMAIN_VIDEO_TYPE_CIRRUS: case VIR_DOMAIN_VIDEO_TYPE_DEFAULT: case VIR_DOMAIN_VIDEO_TYPE_VBOX: case VIR_DOMAIN_VIDEO_TYPE_PARALLELS: diff --git a/src/qemu/qemu_domain.c b/src/qemu/qemu_domain.c index e5c6ef3fda..7f0baf57ac 100644 --- a/src/qemu/qemu_domain.c +++ b/src/qemu/qemu_domain.c @@ -6835,6 +6835,9 @@ qemuDomainDeviceVideoDefPostParse(virDomainVideoDefPtr video, if (video->type == VIR_DOMAIN_VIDEO_TYPE_QXL && !video->vgamem) { video->vgamem = QEMU_QXL_VGAMEM_DEFAULT; + } else if (video->type == VIR_DOMAIN_VIDEO_TYPE_CIRRUS) { + /* cirrus vram is not configurable.

[libvirt] [PATCH 00/15] qemu: Add possibility to control qemu capabilities for debug (blockdev-add saga spin-off)
by Peter Krempa 20 Jun '19

20 Jun '19

While this is not strictly required for blockdev to work it was created as a part of the testing (and possibly regression mitigation) effort. These patches introduce the option to add or remove qemu capabilities via the qemu XML namespace custom elements and remove features via qemu.conf. This series depends (very slightly) on the series deleting qemu parsing. To make applying it easy I'd sugges you fetrch everything needed by: git fetch https://github.com/pipo/libvirt.git features-filter Peter Krempa (15): qemu: Rename qemuDomainCmdlineDefPtr to qemuDomainXmlNsDefPtr qemu: Move qemuDomainXmlNsDef(Free) from qemu_conf.(ch) qemu: domain: Use virStringListFreeCount in qemuDomainXmlNsDefFree qemu: Extract parsing of qemu namespace arguments into separate function qemu: Extract parsing of qemu namespace env vars into separate function qemu: Refactor qemuDomainDefNamespaceParse qemu: domain: Split out commandline namespace data formatting conf: Add taint flag for custom hypervisor features qemu: Add support for controling qemu capabilities via the qemu XML namespace qemu: domain: Add support for modifying qemu capability list via qemu namespace tests: qemuxml2argv: Modernize and fork 'qemu-ns' test tests: qemuxml2argv: Test qemu namespace capability tweaking qemu: Remove unused var 'corestr' from virQEMUDriverConfigLoadFile qemu: conf: Add debug option to allow disabling qemu capabilities qemu: Implement support for 'capability_filters' config option docs/drvqemu.html.in | 30 ++ docs/schemas/domaincommon.rng | 19 ++ src/conf/domain_conf.c | 1 + src/conf/domain_conf.h | 1 + src/qemu/libvirtd_qemu.aug | 3 + src/qemu/qemu.conf | 7 + src/qemu/qemu_command.c | 16 +- src/qemu/qemu_conf.c | 39 ++- src/qemu/qemu_conf.h | 17 +- src/qemu/qemu_domain.c | 285 +++++++++++++----- src/qemu/qemu_domain.h | 19 ++ src/qemu/qemu_process.c | 55 ++++ src/qemu/test_libvirtd_qemu.aug.in | 3 + tests/qemuxml2argvdata/qemu-ns.args | 33 -- .../qemu-ns.x86_64-4.0.0.args | 41 +++ .../qemu-ns.x86_64-latest.args | 41 +++ tests/qemuxml2argvdata/qemu-ns.xml | 5 + tests/qemuxml2argvtest.c | 3 +- 18 files changed, 458 insertions(+), 160 deletions(-) delete mode 100644 tests/qemuxml2argvdata/qemu-ns.args create mode 100644 tests/qemuxml2argvdata/qemu-ns.x86_64-4.0.0.args create mode 100644 tests/qemuxml2argvdata/qemu-ns.x86_64-latest.args -- 2.21.0

[libvirt] [PATCH] remote: refactor how unprivileged user session connection is identified
by Daniel P. Berrangé 20 Jun '19

20 Jun '19

Currently the VIR_DRV_OPEN_REMOTE_USER flag is only set when we identify that we're connecting to a local libvirtd daemon. We would like to be able to set that even if connecting to a remote libvirtd daemon. This entails refactoring the conditional check. One subtle change is that the VIR_DRV_OPEN_REMOTE_USER is now set when the test+XXX:// URI is used, even if a servername is present. This has no effect in this patch, but will later.
